Simply put, the people of this forum tend to be harsh to anyone who has not introduced themselves. Contradicting an established member here would generally be seen as an insult. Regardless of the validity of anything that you would say, it will be interpreted as disrespectful. This forum has rules and the members here tend to enforce them aggressively. I don't mean this as an ultimatum, but if you intend to stay here, your best course of action is to apologize and post an introduction (It doesn't matter if you think what you did was wrong). The members here seem to forgive and forget quickly enough. Otherwise if intend to stay without an apology or introduction, then prepare to have a difficult time interacting here.
